The switching power supply is not installed in the device but externally.
The digital box Imperial HD1 is actually unexpectedly small. More specifically, only width 136mm x height 32mm x depth 100mm.
That relatively small remote I find impractical and fiddly. Who zaps a lot of the programs hereby certainly no great pleasure. The joy would have slowed down in the switching times. The I personally average but tolerable. The picture quality is not great, but fine.
Excluding undeterred, one realizes that this box yet fulfilled its task. Commissioning / Initial goes without problems by hand. Here might even inexperienced users will have no problems. About the Owner's Manual (German) is debatable, that's certainly better, but you can handle it.
The unit has a pre-programmed program list for TV and radio, but unfortunately no LCD display on the front, but only 2 function LEDs. Ie you can not see on the device itself the currently selected program. This can be seen but on the TV screen when switching / switching.
So who looks a lot like TV and change programs should fall back on another device. For the standard required for. As the second television the box is to use but absolutely fine.
